Method and apparatus for winding and removing coreless rolls from a spindle
Abstract:
A coreless roll (12) of a plastic film (10) is directly wound onto a tubular spindle (11); the spindle (11) is provided with an air chamber (11P) having a perforated side wall (11W), which communicate with a pressurised air source (27). At the removal of the roll (12), the inner turns of the roll (12) are radially expanded by feeding a pressurised airflow into the winding spindle (11) and the roll (12); the pressurised air is fed for a length of time required for the removal of the roll (12).
Abstract(Chinese):

塑料薄膜（10）的无芯卷（12）直接缠绕在管状心轴（11）上; 主轴（11）设置有具有穿孔侧壁（11W）的空气室（11P），其与加压空气源（27）连通。 在去除辊（12）时，通过将加压的气流送入卷绕轴（11）和辊（12）中，辊（12）的内圈被径向膨胀。 加压空气被输送一段时间以移除辊（12）所需的时间。
